Improved methodology has been developed for generating controlled test atmospheres. Vaporization of volatile liquids is accomplished in a 28 mm (O.D.) glass J-tube in conjunction with a compressed air flameless heat torch, a pressure-sensitive switch, and a positive displacement piston pump. The vaporization system has been very reliable with a variety of test materials in studies ranging from a few days to several months. The J-tube vaporization assembly minimizes the possibility of thermal decomposition of the test material and affords a better margin of safety when vaporizing potentially explosive materials.
已开发出用于生成可控测试气氛的改进方法。挥发性液体的汽化是在一个外径为28毫米的玻璃J形管中完成的，该J形管与压缩空气无焰加热炬、压敏开关和容积式活塞泵配合使用。在从几天到几个月不等的研究中，该汽化系统对于各种测试材料都非常可靠。J形管汽化组件将测试材料热分解的可能性降至最低，并且在汽化潜在易爆材料时提供了更好的安全边际。
